`perl -p -e 's/^\s+//' < file1 > file2` [download] the -p wraps a while loop reading from standard in with a print $_ at the bottom of whatever you put in -e. in other words `while(<>) { # whatever is in -e print $_; }` [download] /\/\averick perl -l -e "eval pack('h*','072796e6470272f2c5f2c5166756279636b672');"	[reply] [d/l] [select]

If you want things to be munged in place use `-i` `perl -i.bak -pe 's/^\s+//' foo` [download] If you don't want a backup copy, omit the backup suffix. See `perldoc perlrun` for more information.	[reply] [d/l]
